Heat recovery function recycles waste heat from air conditioners
Space savings Air conditioning and hot-water supply in one system – Installation space reduced
Air conditioners normally exhaust hot air from the outdoor unit as waste heat in cooling operation. With Mr. SLIM+, however, the heat that is exhausted
by conventional air conditioning systems is recycled and simultaneously transferred to the hot-water supply system, where it’s used to heat water.
Mr.SLIM+ utilizes an evolutionary “2-in-1” design that combines two original Mitsubishi Electric system technologies (i.e., Air-to-Air and Air-to-Water)
using a single outdoor unit.
In conventional systems, the air-heat exchanger in the outdoor
unit works as a condenser during air conditioning operation.
The heat of the indoor-air is transferred to the outside-air and
exhausted as waste heat.
The new circuit in Mr.SLIM+ uses a water-heat exchanger for
supplying hot water as the condenser. When the air conditioning
and hot-water systems are running at the same time, heat is
recycled and used rather than being exhausted as waste heat.
“COP7.0* attained at water temperature of 45°C and standard air
conditioning operation conditions”
Traditionally, when using a hot-water supply system where the
air-heat exchanger is in the outdoor unit, operation may not be
possible when the outside temperature is very high. However,
since Mr.SLIM+ uses the Air-to-Air indoor unit for air conditioning
operation and there’s no heat exchange with outside-air,
it’s possible to use the hot-water supply system even if the
ambient temperature is very high.
“Hot-water supply is possible (in heat recovery mode) even when
the temperature outside is high (outside temperature = 46°C)”
Save on installation
*Conditions for Air-to-Air coolong: Indoor 27°C (dry bulb) / 19°C (wet bulb) ; Outdoor 35°C (dry bulb) *Water temperrature: 45°C
Mitsubishi Electric’s legendary Air-to-Air and Air-to-Water systems
have been integrated into a new configuration in which two systems
share just one outdoor unit. The installation area required outside is
cut in half, realizing a space savings of 50%.
Conventional system
Save on construction
Previously, two systems including two separate outdoor units were
required. But the all-new Mr.SLIM+ simplifies everything into a single
system configuration, improving reliability and quality by reducing
installation time. That results in savings in both time and money,
which are passed on to our customers.

*1 Refrigerant leakage contributes to climate change. Refrigerant with lower global warming potential (GWP) contributes less to global warming than a
refrigerant with higher GWP if leaked to the atmosphere. This appliance contains a refrigerant fluid with a GWP equal to 1,975. This means that if 1 kg
of this refrigerant fluid leaked to the atmosphere, the impact on global warming would be 1,975 times higher than that of 1 kg of CO 2 over a period of
100 years. Never try to interfere with the refrigerant circuit yourself or disassemble the product yourself; always ask a professional.
*2 Energy consumption based on standard test results. Actual energy consumption will depend on how the appliance is used and where it is located.
*3 Optional air protection guide is required where ambient temperature is lower than -5°C.
*4 SEER/SCOP values are measured based on EN14825.
*5 Ait-to-Water values are measured based on EN14511 (Circulation pump input is not included.).
*6 Conditions for Air-to-Air cooling: Indoor 27°C (dry bulb) /19°C (wet bulb); Outdoor 35°C (dry bulb).
